Visual inspection and pre-warning system for longitudinal tear of conveying belt and application method of conveying belt

Abstract

The invention discloses a visual inspection and pre-warning system for a longitudinal tear of a conveying belt and an application method of the conveying belt and belongs to the technical field of on-line testing of coal mining equipment. The visual inspection and pre-warning system for the longitudinal tear of the conveying belt is characterized in that inspection is performed in the manner that an infrared visual sensor system and advanced RISC machine (ARM) framework-based embedded system platform are combined to accurately judge an ongoing longitudinal tear fault and a hidden dangerous source of the conveying belt; and the conveying belt is inspected and pre-warned from two levels so as to guarantee the safe operation of the conveying belt. According to the system, image information is normally acquired under the dark condition, and therefore, the defect that auxiliary backlight needs to be adopted when a common industrial camera is used in traditional visual inspection is avoided, the defects that a traditional visual inspection instrument is complex to install, is serious in energy consumption, cannot be applied to complicated work environments and is not ideal in inspection effect are overcome, the damage degree of the conveying belt is reduced to the maximum limit, the possibility of accident occurrence and hazards brought after an accident occurs are fundamentally reduced, the safe transport of the conveying belt is comprehensively guaranteed, the work cost is reduced, and the work efficiency is effectively improved.

Description

technical field [0001] A system and an application method for visual detection and early warning of longitudinal tearing of conveyor belts belong to the technical field of online testing of coal mine equipment. It is a combination of infrared vision sensor system and embedded system platform based on ARM architecture to detect, accurately judge the ongoing longitudinal tear fault and hidden danger source of the conveyor belt, and carry out the conveyor belt from two levels Detection and early warning, the technical scheme of the system and application method to ensure the safe operation of the conveyor belt. Background technique [0002] In the production process of coal mine enterprises, the longitudinal tear of the conveyor belt is one of the three major disasters of the belt conveyor. As an important part of the conveyor, the conveyor belt accounts for about 40% of the entire conveyor cost. However, due to the long-term operation of the conveyor belt and various unexpect...

Problems solved by technology

However, these detection methods have the following problems: the detection method is immature, the real-time performance is poor, there are many intermediate links, and the cost is high; the reliability of the mechanical device is low, the number of malfunctions is too many, and the normal production cannot be organized

There is almost no detection of dangerous sources. At present, the iron remover is commonly used for the treatment of dangerous sources, but the iron remover cannot absorb large iron pieces and gangue and other non-magnetic dangerous sources.
